07 crf 450r stuck in gear

By BOBMIL24, Posted April 15, 2009

does anyone know why or what it is gonna take to repair a crf 450 stuck in first gear. I landed hard with my boot on the sfift leaver and it springs up and down but will not change gears.

sounds like you bent/broke the shift fork. Gonna have to split the cases

My money would also be on fork damage. Never heard of it happening in that way before, though

I agree that its probably the shift fork but you dont have to split the cases to remove the shift fork. Just remove the shifter then remove the right side engine cover. You will have to remove the clutch assembly the ratchet mechanism for the shift drum and a couple of gears and it will pop right out.

That's not the shift fork. That is the assembly that cause the drum to turn. He may have broke the shifter pawls or bent something in there that is not allowing the shift drum to turn. If the shift forks need replaced you have to split the cases to remove them.

This little chip out of the shift drum caused 5th gear to go out on my '07. You could always stop once you get the clutch basket off,you can get to the end of the shift drum but any thing else in the tranny is complete disassembly. My shifter wasn't stuck and it all worked except 5th gear.

check your shift shaft 1st. mine was doing the same thing and i was about to split the cases to check the shift forks and i decided to check the shaft, and it was bent/cracked from a similar force as you described.

By BOBMIL24, Posted April 16, 2009

Thanks, for the replys. But can I check the shift shaft with out spliting the case?

My son did the same thing last year and up in Canada it cost him roughly $600.00!

By BOBMIL24, Posted April 16, 2009

what is crazy the shift lever isnt even bent,and springs up and down like it always did.

I meant the end of the shift shaft. Owe quite hitting me. Just kidding man.

Mine recetly wouldn't shift out of first either. I pulled it apart, the Hinson basket backing plates allen bolts backed out shearing against the case. Causing the mainshaft to actually crack the case.

So U Had To Replace The Case?

By BOBMIL24, Posted April 18, 2009

Can I replace the shift shaft with out spliting the cases?

By GMO397, Posted April 19, 2009

Yes I had to replace the case. Yes you can replace the shift shaft without splitting the cases.

By BOBMIL24, Posted April 20, 2009

thanks, I got it. The shift linkage came apart from the shift pin. But I wonder if it supposed to have a shift collar on the shift pen, my 04 has a collar on it but see one on 07, could i be missing something here? could it be in the bottom of the case ? I put it back together and it works fine BUT I AM WORRIED ABOUT the shift collar . Thanks for all the help. I hope I can help someone some day.

By BOBMIL24, Posted April 20, 2009

correction, I didnt see one on the 07.(shift collar on the shift pen)

I realize this thread is a year old... but I assume you broke the shift collar (part number 10 on the attached). Did you put a new one on there? Did you replace anything else, and have you been trouble free since? Same thing happened to my husband's '06 this weekend. Collar broke, so he is replacing the gearshift spindle (part 18) and a new collar (10).

I'm hoping I can revive this thread. I have an 05 450x and this past weekend I started having a shifting issue. 1-2nd are fine but to get it into 3-5th you have to push the shifter towards the case with your foot or even your hand while on a stand. The fact that it does shift but you just have to push the shifter in makes me think it's not the forks or drum. This started happening after my rear wheel bearings exploded and the chain came off and got wedged between the shifter and front sprocket. Any sugesstions on where to start looking would be appreciated.

Thanks

This would have been a better new thread.

But, pull the clutch cover and the inner cover and the hub and basket to see whats happening the shifter ARM coming off the shifter shaft. You may have a problem with the ratchet if it works in first and second but not correctly in 3rd through 5th. And thats an easy fix. The cases dont have to come apart, the engine doesnt even need to come out of the chassis.

If there isnt anything wrong with the ratchet, well...you'll have to pull the engine and split the cases. You might have a broken shifter drum. The drum will break from the shift fork being slammed over in its groove in the drum and not even bend the fork sometimes.
